Abstract

PURPOSE: To prevent damage to teeth, and obtain a positive engagement by providing strap segments having teeth of a locking member, capable of engagingly locking, at the end parts of a fixed member, and providing nutually engageable toothed closure tongues on the outer portions of the strap segments, which are provided with an external teeth and an internal teeth. CONSTITUTION: A connecting supports 3 are provided at a fixed member 1 comprising a baseplate 2, and the end parts of the supports extend to form strap segments 4 4', the strap segments are divided into outer end portions 6 and inner end portion 5. The outer end portions 6 extend to two parallel toothed closure tongues 11, 12, 13, 14 alternately provided with external toothed teeth and internal toothed teeth. Since the free ends of the closure tongues are formed to be diagonal-cut faces 11', 12', 13', 14', cooperating closure tongues can be easily correctly lapped with each other. As a result, a plurality of abut on a mating strap, the face pressure is reduced and damage to teeth can be prevented even when a heavy load accompanied by vibration or impulsive force is applied.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a tube retainer according to the preamble of claim 1.

(Prior art) This type of pipe holder is, for example, the Swiss patent pipe 643.33
It is known from No. 8. One clamp segment of the tube holder is provided with an outer tooth row that has one tooth;
On the other hand, another clamping segment is provided with an inner toothing having two teeth. In order to accommodate pipes of larger dimensions, the inner toothing of this known pipe holder can be enlarged. That is, there will be a hollow space between the pipe and the unused portion of the inner toothing, so that the pipe will not be surrounded in a tight manner. The supporting function of this known pipe holder is non-uniform in the longitudinal direction of the pipe with respect to the central plane. Therefore, if the four lateral skirts are large, it is difficult to make the tooth rows fit perfectly.

(Problems to be Solved by the Invention) In view of the above circumstances, an object of the present invention is to provide a tube holder equipped with a locking mechanism that eliminates this drawback.

(Means and operations for solving the problem) This object is achieved by the configuration disclosed in the characterizing part of claim 1. The locking mechanism is divided into two identical locking pieces juxtaposed symmetrically about a central axis perpendicular to the fixing member.

In the case of the embodiment according to claim 2, even if the locking mechanism has small geometric dimensions, the surface pressure on each tooth can be reduced, so it is possible to avoid the risk of crushing the synthetic resin teeth. .

In the case of a particularly preferred embodiment according to claim 3, there is no point of action for auxiliary means (for example a screwdriver, a coin), so that accidental opening of the tube retainer is avoided. That is, the locking mechanism can only be opened using a special tool, thus significantly increasing the reliability before piping.

In the case of the embodiment described in claim 4, the more the tooth rows are disengaged, the more the mutually engaging lock pieces cannot be slid against each other at right angles to the longitudinal direction. Unlocking is thus avoided, especially when pivoting the pipe around an axis perpendicular to the fixing member.

Further preferred embodiments of the tube holder are disclosed in separate claims.

(Example) Embodiments of the present invention will be described based on the drawings.

The pipe holder shown in FIGS. 1 and 2 has a fixing member (generally designated 1) including a base plate 2 provided with connecting posts 3 on both sides. Connecting column 3 on the opposite side of base plate 2
the ends of which extend into clamp segments 4, 4';
The segment is thus divided into an inner end 5 and an outer end 6.

The base plate 2 is provided with an abutting protrusion 7 and an opposing receiver 8 (the functions of which will be explained below together with the introduction of the pipe).

The connecting strut 3 is configured to be flexible in the manner of a leaf spring and is rigidly connected at the strut end to the base plate 1 2 and to the clamping segment 4.4'. Therefore, the clamping segments 4° 4' can be moved in response to the deformation of the connecting strut 4. In this case, the strut portion 9 following the base plate 2 is reinforced so that it will not bend or buckle despite its slender structure. Furthermore, the connecting strut 3 has an outwardly curved portion 10, so that the clamping segment 44' has a figure 7 shape in the open position and thus the figure 7-shaped expanded clamp segments 4, 4'. Pipes can be introduced and installed between them.

Each empty outer end 6 has two parallel locking pieces 1.1.12; 13 with alternating saw-toothed outer and inner toothings.
．． I'm off to 14. Therefore, the opposing lock pieces 11, 14: 12, 13 having corresponding structures can be combined in a known manner to achieve a locked state. In this case, the locking piece 11.13 with external toothing has a longer toothing range in order to ensure an engagement range adapted to various pipe diameters. The free ends of the locking pieces 1i, 12.13.14 have corresponding beveled surfaces 11', 12', respectively.
13', 14' and thus the cooperating locking pieces 11.14: 12.13 can facilitate correct weighting.

The inner end 5 has a hook 15 that engages the abutment projection 7, so that overloading of the connecting strut 3 is avoided in case of extremely high lateral forces. Furthermore, since the inner end is more strongly curved and more rigid than the outer end 6,
It flexes and conforms to the contour of the pipe only under load from the inlet pipe.

Since the inner end 5 is configured in the shape of a fork, the fixing elements (eg screws, etc.) installed on the fixing member 1 can be operated from the outside with a tool.

FIG. 3 shows the state when the pipe 16 is introduced into the pipe holder. The pipe 16, which is pressed into the pipe holder in the direction of the arrow P, exerts a force on the end 5 directed towards the fixing member 1, with the result that a moment is exerted on the more outwardly located clamping segments 4, 4'. Now, the connecting strut 3 is the clamp segment 4
, 4', the bending moment is
It is introduced into the clamp segment and deforms the clamp segment, so that the clamp segment curves inwardly, ie in the closing direction. The holding point at which the connecting strut 3 connects to the clamping segment 4.4' is thus moved inwardly. That is, clamp segment 4°4'
are raised upright from the V-position by a pivoting movement and approach each other in a scissor-like movement, thus gradually gripping the pipe 16 between them. This movement is assisted by the stronger curvature and stiffer configuration of the inner end 6.

FIG. 3 shows a state in which the pipe 16 is displaced to the side 'C' relative to the clamp segment 4 due to supplementary lateral forces. This type of condition can actually cause heavy and difficult to handle pipes 16
This is likely to occur in cases of However, due to the attachment force directed towards the fixing member 1, the clamp segment 4 is
Standing upright, the pipe 16 is introduced into the interior of the pipe holder against lateral forces. The inner end 5 is thus pushed down progressively by the same amount by the pipe 16, so that the locking pieces 11.12.13.14 abut at the same height and in the same stroke, locking A possible state is achieved. The radius of curvature of the clamping segment 4.4' is smaller than the radius of the pipe 16 to be surrounded, so that said pipe is surrounded under normal load and the locking piece 11.12: 13.
The free end of 14 fits tightly against pipe 16. If the pipe 16 is further slightly press-fitted into the pipe holder, the lock will be reliably established, and the opposing pairs of locking pieces 11° 14: 12.
A double locking mechanism from 1.3 helps ensure locking, with the pipe 16 connecting the clamping segments 4,
After locking the lock member 4', first, it is simply loosely surrounded,
Due to the movement of the pipe, a load is applied to the locking member, and the °C also increases.
The lock will never come off.

FIG. 4 shows the pipe holder with the pipe 16 inserted therein.The upper end 6 forms a loop surrounding the pipe 16 together with the locking pieces 11, 12, 13 degrees 14. Counter supports 8 and abutment projections 7, which prevent overstretching of the ends 5 and the connecting struts 3, serve to protect against excessive forces acting on the pipe 16.

Furthermore, although the present invention has been described for use as a pipe holder,
It can also be used to fixedly support wire rods, etc. outside the front side.

(Effects of the Invention) The present invention provides mutually parallel locking pieces having alternating outer tooth rows and inner tooth rows at the end of the clamp segment, so that in the lock position, a plurality of teeth of the tooth row come into contact with each other. Due to the contact, the surface pressure is reduced and the risk of crushing of the plastic teeth is therefore avoided even under high loads such as vibrations or impact forces.

During engagement of the tooth rows, the beveled surfaces 12', 14' abut against the gentle tooth flanks of the locking pieces 11.13 of the other clamping segments h4, 4' and do not protrude from the next steep tooth flank. . Therefore, for example, by a screwdriver or a coin,
Unwarranted opening of locks, especially one-handed locks, is avoided.

This is because there is no point of action for the above-mentioned auxiliary means.

Furthermore, since the lateral spacing between the locking pieces is small, the locking pieces cannot be slid against each other until the tooth rows are disengaged, so that accidental unlocking of the tube holder is unlikely to occur. The lock piece is of a type in which each clamp segment is fixed by a hinge installed between an outer end far from the fixing member and an inner end close to the fixing member, as described in Swiss Patent No. 643,338. It can also be provided in the clamping segment of the known pipe holder.
